Abstract
Forty-eight extracted human teeth were prepared for study to compare ketac Endo cement with Grossman's cement in preventing leakage of a dye. Four groups were formed: (1) Grossman's sealer with a single gutta percha cone; (2) Grossman's sealer with lateral condensation of gutta percha; (3) Ketac Endo sealer with a single cone of gutta percha; and (4) Ketac Endo sealer with lateral condensation of gutta percha. The teeth were immersed in the dye for 10 days, after which they were rinsed in running tap water and cleared for observation. In the groups of teeth evaluated by three individual evaluators, the results consistently showed less leakage with glass ionomer sealers (groups 3 and 4) than with the Grossman's sealers (groups 1 and 2). The best results were noted when Ketac Endo sealers were used with lateral condensation.
